域上稳定映射的模

Moduli of stable maps with fields

Renata Picciotto

摘要:

我们构造了一个稳定映射的模空间,其域与一个射影簇的三元组$(X,E,s)$(或具有射影模空间的DM栈)、一个向量丛和一个截面相关联。证明了该类与$Z=Z(s)\subset X$稳定映射的模空间上的虚基本类在符号上一致。我们表明,这给出了量子Lefschetz超平面原理的推广。这推广了Chang-Li,Kim-Oh和Chang-Li的类似比较结果,并提出了不同于Chen-Janda-Webb的方法.

英文摘要:

We construct a moduli space of stable maps with fields associated to a triple $(X,E,s)$ of a projective variety (or a DM stack with projective moduli space) a vector bundle and a section. We show the class coincides up to a sign with the virtual fundamental class on the moduli space of stable maps to $Z=Z(s)\subset X$. We show that this gives a generalization of the Quantum Lefschetz hyperplane principle. This generalizes similar comparison results of Chang--Li, Kim--Oh and Chang--Li and presents a different approach from Chen--Janda--Webb.
